VAPORIZING DEVICE FOR EXPLOSIVE-ENGINFES.

SPECIFICATION formingpart of Letters Patent N o. 709,126, dated September 16, 1902.

Application filed July 13,1896.

To al?,` whom, tm/tty concern:

Be it known that L'BENJAMIN C. VANDU' ZEN, a citizen of the United States, and a resident of the villageV ofWinton Place, in the county ofHamilton andStatelof Ohio, have invented certain new and useful `Improvements in Gasolene-Engines, of Vwhich the following is a specification.v

The several features of my invention and the various advantages resulting from theirV use, conjointly or otherwise, will .be apparent from the following description and claims.

Referring to the accompanying drawings, making a part of this speciiioation, and to which reference is hereby made, on Sheet l Figure l represents a side elevation of a machine embodyingr my invention. Fig. 2, Sheet 2, represents a top view of the same machine. Fig. 3, Sheet 3, represents an end view of the same. Fig. 4c, same sheet, and Figs. 5 and 6 of Sheet 4 are enlarged views of the mixingchamber and valves whereby air and gas are admitted to the chamber and duly mixed.` Fig. 7, Sheet/1, is a view of the under side of the lower valve of the diaphragm of the mixing-chamber. Fig. 8, Sheet 1, shows enlarged an edge View o t certain cams respectively usedfor operating the exhaust-valve and the electric lighter. A

There is present for this engine a suitable base and frameA, one or more fly-wheels B, shaft C thereof, operated by a crank O3, connected by a connecting-rod O3 to the piston D, reciprocating within a cylinder D3. The latter is preferably provided, as shown, with the customary water-spaces, as D3, forming a Water-jacket, through which cool Water passes and keeps the cylinder cool. The `cylinder has an exhaust-pipe E, whose valve E3 is duly operated through agency of the rod E3 by the cam E4 on shaft E3, duly operated by gear E3 E7 from the crankshaft C or other suitable source. One end of the rod E3 carries a roller E3B, which bearing on the cam E4 reduces f go JG, surrounding the conduit H3.

Serial NoI` 598,958. (No model.)

tions thereof, such parts and their accessories will now receive particular description.

H is the gasolene-inlet pipe, conveying the gasolene to and into the vertical pipe H3. This pipe has a regulating-screw H3, carrying a valve 113V, operated by hand-wheel H4. By screwing the valve II3V downward the opening'for the passage of gasolene can be diminished at will, and by elevating it the opening is enlarged. The conduit H3 is gradually narrowed at lI3S, forming a valve-seat for the valve H3V. The conduit H3 is finally contracted to a minute orifice I, through which the gasolene in minute quantities passes down. The lower part of the orifice is conically enlarged at I3 into avalve-seat. Below this seat is a conical valve J, fitting said seat and supported by strap or bracket J3 J3 from a pist-on J 3,whose edge (periphery) fits against the side J4 of an annular chamber J4C. A ledge `J 3, below the edge of the piston, operates as a stop to prevent the piston from falling too far. The piston is connected above with meansfor raising it, and lthe preferred means for thispurpose are two lugs J7, connected to the piston J3 by means of a sleeve The under faces J8 0f these lugs, as shown, engage `the inclined faces K3 of the tines K3 of the bifurcated rod K, longitudinally reciprocated by the governor, as hereinafter mentioned. The advance of the rod K limits the descent of the piston J3. The rod K rests upon an abutment J", preferably the roof of the chamV ber. The necessary amount of gasolene for running the engine at the desired rate of speed having been ascertained, the wedge is fixed in connection with the governor. When the engine is going too fast, the governor interposes more of the wedge K3 of the rod K beneath the lugs J7, and thus diminishes the supply of gasolene to the mixing-chamber and raises the piston J 3, and as the wedge K3 is still farther interposed the valve J is lifted into its seat in the lower portion of the conduit I, thereby stopping the flow of gasolene through this conduit I. As the engine slows down the wedge is more and more withdrawn and the valve J is lowered more and more, andthe supply of gasolene to the 'mixing chamber is correspondingly increased. In

IOO

this way the governor governs the admission of gasolene into the m'ixingchamberand thus controls the power and speed of the exigirle. The piston will remain elevated through the agency of the springs L L until the formation of a vacuum more or less perfect causes the pressure of the atmosphere external to the piston to press the latter' down. At such a time the Valve J is dropped and gasolene through the orifice I is free to enter the mixingchamber. Each spring L is at one end connected to a lug L2 or the like of the piston connections and at the other end to a stud L3 on the pipe H2. The limbs L4 L4 ofthe spring are respectivelylocated in holes, one in the lug L2 and one in the stud L2, and are capable of sliding adjustably through the same. The distance the limbs LL project through their respective holes having been decided upon, they are held there by the setscrew L5 of stud L3, screwed into the latter and bearing against the adjacent limb of the spring. By setting the spring farther forward or backward I am enabled to increase or diminish the elastic tension of the spring, and thus regulate the amount of atmospheric pressure required to open (or drop) the piston.

In the bottom of the mixing-chamber is a large discal valve M of a conical form. The convex center M2 of this valve M is in a vertical line beneath the orifice I, while the edge of this valve overlaps the upper face N of the edge of conduit P, whereby air is admitted to the mixing-chamber. These faces N incline from the axis of the conduit P outward and downward, and the under face M3 of the edge portion ot' the valve is likewise inclined from its edge upward land inward. These meeting faces M3 and N form when together a tight joint. When the air-valve M lifts, the piston drops and valve J drops, and gasolene is by the latter valve admitted to the mixingcham ber,aud as it falls down across the chamber it is met by the u-prushing air admitted through valve M and is vaporized. Any gasolene not thus vaporized drops down on the central portion ot' the valve M and running down the face of the valve and off the edge gathers in the channel N2 at the foot of the inclined face. When thevair-valve M is lifted, the air from pipe P enters between the face M3 of the valve and face N of the seat and catches and mingles with the gasolene dripping from the edge of the valve'and also rushes down into and takes up any gasolene in the channel N2. The rapid current or intake of the air thus brought into contact with the gasolene causes the gasolene to be im- I projects below. A coiled spring M5 embraces the rod below the sleeve P2 and above the pins or lugs M2, the sleeve P2 and the lugs M(i being the abutments between which the spring is compressed. In order to open the valve, the vacuum within the mixing-chamber must be such as to cause the pressure of the atmosphere without to overcome the force ot` the spring. Then the valve, restrained by the spring M5, lifts sufficiently to allow the air from pipe P to enter.

The mixing-chamber is connected to the cylinder-space over the piston by conduit or interconnecting chamber G2. The chamber G, provided with the valve M in its lower portion and the valve J, strap J2, and piston J3 at its upper portion, constitutes the mixing-Y chamber. i

What I claim as new and of my invention, and desire to secure by Letters Patent, is-

l. The combination of the mixing-chamber G, piston in chamber or guideway J4, stop below the piston, valve J, gasolene-inlet conduit H2 constricted at I, and conical valve H2 for regulating the passage of gasolene through the conduit H2, and having a conical seat in the said conduit-pipe, springs L, having one branch connected to the piston and one branch to a ixed point as L2, substantially as and for the purposes specified.

2. The combination of the mixing-chamber G, piston in chamber or guideway J4, stop below the piston, valve J, gasolene-conduit H2 constricted at I, and valve H3 for regulating the passage of gasolene through the conduit H2, and springs L, having one branch connected to and slidable through the extension L2 of the piston, and the other branch con` nected to a stationary stud L3, and having an opening through which the other branch L4 of the spring is slidable, and set-screw for setting the adjustment of the spring, substantially as and for the purposes specified.

3. The combination of the mixing-chamber, Y

gasolene-inlet conduit, dropable valve for controlling admission of gasolene therefrom to the mixing-chamber, sleeve connected to the piston and embracing the inlet-conduit, spring connected to the sleeve and to a ixed detent, the dropable valve supported by the piston, substantially as and for the purposes specified.

4:. The combination of the mixing-chamber, inlet gasolene-conduit, movable piston, carrying valve, controlling the admission of gasolene through the conduit, abutment, wedge resting thereon, and abutments or lugs connected to the piston for engagement with the wedge, and the governor, and means for enabling the governor to reciprocate the wedge and control the drop of the piston, and elastic means'for holding up the piston and valve,

except when the suction in the mixing-chamber opens it, substantially as and for the purposes specified.

5. The combination of the mixing-chamber ing its upper end inclined outward and down- I5 ward forming a tight'seat for the Valve M,

when closed, and having an annular channel below and adjacent to the peripheral edge of the valve M, and an inlet gasolene conical valve, and a dropalole valve supported by the zo piston, and in vertical line abovethe central portion of the air-inlet valve, substantially as and for the purposes specified.
